The DBH 1205/85 is a single-lip radial shaft seal that fits on a rotating shaft and presses into the housing to keep lubricant in and contaminants out. The designation gives the three key dimensions: shaft 27 mm, housing 42.70 mm, height 7.90 mm. This seal is used in gearboxes, pumps, electric motors and other power transmission equipment where bearings need protection.

The part number 1205/85 follows the Mx design. The seal has a sealing lip that runs against the shaft and an outer diameter that is press-fitted into the housing. Its compact section suits assemblies where space is limited and a taller seal would not fit. DBH is a brand we supply, and the part number is ordered exactly as shown.

Typical applications include gearboxes, centrifugal pumps, electric motors, reducers, mixers and conveyors. The seal performs two functions: it retains oil or grease inside the assembly and blocks dust, water and particles from entering. This protection is critical because contamination is a common cause of premature bearing failure.

For proper installation, inspect the shaft for burrs or deep marks in the contact area and make sure the housing is clean and undistorted. Lubricate the lip before inserting the seal, and use a flat tool that presses on the outer diameter, never on the lip. If the shaft shows wear, a seal with an offset lip may be an option. Selection also depends on speed, temperature and lubricant type, so it is worth confirming these details before requesting a quote.

If part number 1205/85 is not the one you need, we can help you find an equivalent within the same radial shaft seal category. To do this, send the measured shaft diameter, housing diameter and height, along with a photo of the old seal and the lubricant used. With that information, we compare options and propose the best fit for your assembly.
